Product Overview
The wuyi single-seat control valve features a top-guided balanced plug design with highstrength,heavy load capacity,S-type flow path,low pressure loss,large flow coefficient,wide control range,and high flow characteristic precision.It is ideal for low differential pressure conditions,ensuring tight shut-off and accurate flow or pressure regulation.
Key Features
WUYI's valves adopt a cage-retained seat structure, offering high reliability and easy maintenance. This design solves the problem of non-replaceable seats in traditional valves, effectively extending service life. With a flow-to-open design, the medium moves in the direction of valve opening, ensuring good control at small openings and minimal flow characteristic distortion. Electric or pneumatic actuators can be selected based on working conditions.
